Zinc Application

Three treatments were used in two-year (2014–2015) field experiments with broccoli cv. Bejo 2914 F1: (1) untreated control; (2) Zn<sub>0.75</sub> – Zinkuran SC as foliar fertiliser at the rate of 0.75 L/ha (375 g Zn/ha); (3) Zn<sub>1.50</sub> – Zinkuran SC as foliar fertiliser at the rate of 1.50 L/ha (750 g Zn/ha). The statistically significant differences of individual broccoli parameters were found after zinc applications. In both experimental years the yield of broccoli with additional zinc fertilisation was significantly higher by about 8.2–14.4% (Zn<sub>0.75</sub>) and 12.5–17.5% (Zn<sub>1.50</sub>), respectively, than in the control. Foliar zinc application significantly increased the sulforaphane content in broccoli florets by about 19.8–32.9% (Zn<sub>0.75</sub>) and 37.2–49.3% (Zn<sub>1.50</sub>), respectively, compared to the control. By contrast, the content of total polyphenolics (of about 9.0–12.5% (Zn<sub>0.75</sub>) and 33.9–35.2% (Zn<sub>1.50</sub>)) and antioxidant activity (Zn<sub>0.75</sub> (3.7–4.2%) and Zn<sub>1.50</sub> (5.3–7.0)) decreased as a result of zinc fertilisation. The investigations pointed to zinc as a very important micronutrient with strong influence on the yield and chosen qualitative, health promoting parameters of broccoli.

AbstractFoliar application of micronutrient is a rapid and promising strategy to enhance the concentration and bioavailability of micronutrients in wheat grain. To explore the effects of foliar application of micronutrients on the concentration and bioavailability of zinc and iron in grain in wheat cultivars and landraces, field experiments were carried out using 65 wheat cultivars and 28 landraces to assess the effects of foliar application of zinc (iron) on phytic acid concentrations, zinc (iron) concentrations and their molar ratios. The results indicated that mean grain zinc concentration of landraces (44.83 mg kg−1) was 11.13% greater than that of cultivars (40.34 mg kg−1) on average across seasons, while grain iron concentration did not differ significantly between landraces (41.00 mg kg−1) and cultivars (39.43 mg kg−1). Foliar zinc application significantly improved the concentration and bioavailability of zinc in grains in both cultivars and landraces, while landraces had almost two-fold more increase in grain zinc and also greater improvement in zinc bioavailability compared to cultivars. While foliar iron application did not significantly affect iron concentration and bioavailability in grains in either cultivars or landraces. Our study showed that, with foliar application of zinc but not iron, wheat landraces had better performance than cultivars in terms of the increases in both concentration and bioavailability of micronutrient in grains.

Zinc Application

Agronomic zinc (Zn) biofortification of crops could help to alleviate dietary Zn deficiency, which is likely to affect more than one billion people worldwide. To evaluate the efficiency of agronomic Zn biofortification of broccoli, four application treatments were tested: no Zn application (control); soil application of 5 mg/kg ZnSO<sub>4</sub>·7 H<sub>2</sub>O (soil); two sprays (15 mL/pot each) of 0.25% (w/v) ZnSO<sub>4</sub>·7 H<sub>2</sub>O (foliar); and soil + foliar combination. Soil Zn application increased Zn-DTPA (diethylenetriamine pentaacetic acid) concentration by 3.7-times but did not affect plant growth or plant Zn concentration. Foliar Zn application increased stem + leaves and floret Zn concentration by 78 and 23 mg Zn/kg, respectively, with good bioavailability based on phytic acid concentration. Boiling decreased mineral concentration by 19%, but increased bioavailability by decreasing the phytic acid concentration. The entire broccoli could constitute a good nutritional source for animals and humans. An intake of 100 g boiled florets treated with the foliar treatment will cover about 36% of recommended dietary intake (RDI) of Zn, together with 30% of Ca, 94% of K, 32% of Mg, 6% of Na, 55% of P, 60% of S, 10% of Cu, 22% of Fe, 43% of Mn, and 35% of Se RDIs.
